If you mean impulse type, Champion will give you the best long term performance. The NAAN looks ok, but is a homeowner product just like the orbit or rainbird. Impulse heads are much less in vogue now, either commercially or residentially, because the are not the best in even distribution or water conservation.

For Rotor heads, go Toro. The Rainbird rain-curtain rotors are pretty good also.

Gosh, I have some Rain Bird impulse sprinklers that have been working since 1984. I would consider that fairly reliable. Toro and Hunter have very good reputations as well, but I've never used them myself. I think it is pretty much up to individual preference.

These Israeli heads I have come from a professional supply house, and have a better pattern and adjustability. I have gotten 4 or 5 years from some, and usually the issue is breakage from some sort of impact anyway.
